Context

Unlike an immovable osseointegrated dental implant, tooth auto-transplantation provides vital periodontium and continuous skeletal growth (1).
Many factors could influence the longevity of and incidences of complications with tooth auto-transplantation and failure rates (FRs) reported in the literatures are not identical.
Incidences of infection-related root resorption and ankyloses varied among studies.
Effects of a systemic antibiotics (SA) regimen, endodontic treatment, splinting protocols and the morphology of the donor tooth on outcomes of tooth auto-transplantation are still in question.

Purpose of the Review 

Assess the clinical outcomes of auto-transplanted teeth with complete root formation and the effects of various influencing factors.

Key Findings

  • Tooth auto-transplantation with complete root formation is a favourable treatment with rare failure rate (FR), infection-related root resorption rate (RR) and ankylosis rate (AR).
  • However, systemic antibiotics (SAs), endodontic and splinting modalities and tooth morphology seemed to influence the outcomes.

  1. Only tried this once in my practice. Limited patient pool interested in the procedure. It was a stand alone cuspid that I autorotaded into place and left it alone. Looked good but was painful for the patient. A few years later it was an abutment for a bridge and then it started ankylosing. Overall it was ok but implants are a simpler and easier modality.

  2. Could the author expand on the definition of an auto-transplanted tooth,and the procedure involved?
    I find this article is too vague

  3. I’d love to know of articles or clinical guidebook describing the proper technique for auto-transplantation as well.
